Simplify gateway code (handles interrupts internally) and remove external dependencies. Ledmode is now always "enabled".

Remove unused libraries.
Add default CS/CE pin to Config.h
Add new variebles for voltage and current.
Add new internal command sent to controller when gateway is ready and online
